T o all whom t may concern.'

Be it known that I LEWIS A. CHAMeER- LIN a citizen of the nited States, residing at e Soto, in the county of Jefferson and State of Missouri, have invented certain new and useful Improvements in Heel-Fastening Devices; and I do declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

rIhis invention relates'to an improved heel fastening device especially designed for permanently securing wooden heels to shoes, slippers, and the like, but not to be restricted to this particular use since it will well serve to connect many other members together.

Ordinarily, wooden heels, such as French heels, are secured to the upper, or rather to the sole, by glue. They are also fastened in place by nailing, both methods'being crude and unsatisfactory because in most cases, if the heel is glued in place it does not stay on long, especially if it is hit against obstructions, such'as curbs, car steps and the like, which accidents often occur. zhey are nailed, or similarly fastened on, `shey stay on better, but this method is bad oecause the heels are so often split during bheirattachment to the upper. .The last nethod is expensive because the split heels iave to be thrown away.

It is my intention and the object of this nventi-on to overcome the above unnecessary circumstances by the employment of iovel fastening means which will permaiently secure the heel in place and yet ob.- Jiate the liability of the heel becoming split )y its use; the fastening means being such ',hat it will facilitate the attachment of ieels, because of the fact that it will clamp yhe heel in place while the glue sets, also, )ecause the fastening will be effected by nerely forcing the heel and sole together. n view of the fact that it is placed in the itrongest part of the heel it will overcome my possibility of the heel splitting.

Another object of the invention is to pro- 7ide a heel fastening device which is simple .nd effective, strong, durable, and inexpenive; o-ne which will reinforce the heel, and vhich is such that it will enable unskilled )ersons to put on their own heels.

Other objects and advantages of the in- 'ention will be apparent during the course if the following description.

When

the position of the parts when the device is effective.

Fig. 3 is a top plan view of one of the parts of the fastener.

Fig. 4 is a detail perspective view ofthe v parts of the fastener.

In the drawings, wherein for. the purpose of illustration is shown a preferred embodiment of my invention, the numeral l designates a portion of the upper of a shoe or slipper and the numeral 2 denotes the sole thereof. Indicated by 3 is a woodenl heel of the French heel type with which my improved fastener is shown in use.

-My improved fastening'device includes a cylindrical stud 4: which is formed in its lower end with a socket and is carried by anon-circular plate 5. The ^latter is adapted for attachment to the exterior of the sole 2, while the stud is designed to be projected into a vertical socket 6 formed in the upper portion of the heel 3. The lower end of the socket .is undercut at 7 to. produce a continuous shoulder, and a cone-shaped spreader 8 including a flat circular base is Ito be placed in the bottom of this bore or socket to expand the lower edge of the stud beneath said shoulder when the heel and ysole are forced together sufficiently hard enough. In addition to the socket, the heel kis also provided in its upper face with a shown. Next, the heel will be brought inplay by inserting the stud 4 into the socket 6, whereupon the heel and sole members will be forced together so as to cause the lower end of the tube to engage the base of the spreader 8 and expand in the manner shown in Fig. 2. The heel will then remain peimanently in place. It is to be understood that the spreader 8 may either be placed in the socket before the sole and heel are brought together, or, it may be forced into the end of the tube L preparatory to the fastening of the heel. Either way will be satisfactory. y

My heel fastening device will be found extremely useful and satisfactory in many respects because it will permit the heel to be easily and readily attached. Furthermore it will reinforce the heel rather than weaken it as the ordinary nail fastenings do. It is light in weight and will take the place of a clamp, in that it will hold the heel tightly in position while the glue sets. Then again, it will positively prevent splitting of the lheel when the latter is being attached. Not

only that, but it will retain the heel in place much longer than the fastenings now in use.

A careful consideration of the foregoing description taken in connection with the accompanying drawings will enable the reader to acquire a clear understanding of the construction and use of the device. In view of this, it is believed that a more lengthy description is unnecessary.

It is to be understood that the form of my invention herein shown and described, is to be taken as a preferred form of the same and that various minor changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or the scope of the subjined claims.

I claim:

1. In combination, a shoe including a sole, an attaching plate secured to the under face of the heel attaching portion o f the sole, a heelformed in its upper face with a recess receiving the plate therein, said heel being also provided with a vertical socket, the inner end of which is increased in diameter to provide a continuous shoulder, a depending stud rigidly connected to the attaching plate and extending into the socket, having a socket formed in its lower end,'said stud being eccentrically disposed with respect to the periphery of the plate, and a conical spreader seated in the bottom-of said first socket and extending into the socket in said ner/aser stud, serving to expand the lower edge of said stud beneath the shoulder when the heel is forced against the sole.

2. A device of the class described comprising anon-circular flat attaching plate provided with a central laterally and eccentrically disposed solid cylindrical stud formed at its lower end with a socket, the lower end of said stud being continuous and uninterrupted, said plate being intended for permanent connection to a member,- a second member designed to bear tightly against and be connected to said first named member, said second member being formed with a central vertical cylindrical socket adjacentits upper end, the inner end of said socket being undercut to form a continuous uninterrupted shoulder, said stud being adapted to. extend into the socket and slightly beyond the shoulder, the last named member having a shallow recess formed in its upper face of a shape corresponding to the aforesaid plate, said recess being intended to receive the plate therein and prevent relative rotation of the members and in turn prevent rotation of the stud in the socket, and a spreader seated in the socket including a conical por-l tion to extend into the socket in the lower end of said stud and a base having a flat upper face intended to roll the inner end of the stud when the two members are forced together so as to form a continuous uninterrupted retaining bead which will extend beneath said shoulder and connect the members together.

3. A fastening device of the class described comprising attaching means, a laterally disposed cylindrical solid stud rigidly 1- connected thereto, being formed in its lower end with a socket, a member including a socket intowhich the stud extends, the inner end of saidfsocket being enlarged to rovide a continuous shoulder, and a sprea er disposed in the socket, including a conical portion to extend into the' socket in the stud, and a flat circular base for engaging and rolling the lower edge of said stu beneath the shoulder, thereby' forming a continuous retaining bead.

In testimony whereof I have hereunto set my hand.
